Nice! Hope you enjoy your new camera. Obviously lots of requests in the thread, hope you don't mind me adding to them by asking for some shots that really test out the dynamic range.

Also, can anyone explain the significance of the Linux OS on the camera? Will this give us any new options, apps, hacks etc?

Linux OS, smaller, simpler, faster.

Technically Linux is not OS, really, as most people understand OS. Linux is just kernel. It's free so almost everyone uses it (phones, cars, cameras, washing machines -- if they have a chip --, refrigerators , every router ever made). The manufacturer doesn't have to display "Open Source" notice if they are using just the Linux kernel.

How do you know that most cameras don't already run on some version of Linux kernel? Everyone already owns something that is running Linux Kernel -- even if they don't know it.

The Linux kernel will boot the computer, for example, but it will be black screen and no way to communicate with the computer. The computer would need other software without which the linux kernel itself is useless.

Richard Stallman is correct that it is unfair (in fact stupid) to call all "Linux" based operating system (like Ubuntu, Red Hat, etc ): "Linux". They should be called GNU/Linux because without the software provided by GNU the kernel by itself won't do crap. The kernel just controls the hardware at very low level. It does nothing else. Linus Torvalds could not have even compiled the first Linux kernel that he wrote in 1991 without GNU C compiler written by Richard Stallman a few years before in late 80s.

Android uses Linux kernel but most people would not recognize it as "Linux" (when they actually mean is "Unix-like operating systems" i.e GNU/Linux) . Even though the kernel is Linux, Android is just Java apps running on dalvik virtual machine. Some people (and this have been done) replaced the Linux kernel on Android phone with BSD kernel and the phone still behaves just like an Android phone.

>Linux OS, smaller, simpler, faster.

Linux is just a kernel. And Linux kernel is not "small". It's a huge, monolithic kernel.
